I have recently had an issue from an update around that time which had this [completion](https://code.visualstudio.com/docs/copilot/ai-powered-suggestions) added with a green tab:
For this specific problem, go to settings.json, User, then search for @tag:nextEditSuggestion and change the following setting from Editor>Inline Suggest>Edits: Allow Code Shifting from always to never.
How I easily accessed the menu was when the green tab came up came up, hover over it and click settings.
Note - to activate the changes, I had to close the file after changing the settings and re open the file.
